Theodor Seuss Geisel, better known as Dr. Seuss, wrote dozens of children’s books that still today reach best seller’s lists and thrill a new generation of fans each and every year. His work, however, as a songwriter is not as celebrated. But when reminded, the songs penned by Seuss are just as enduring and whimsical as his books.

Of course, Seuss did not write the music, only the words, so his credit is in the lyrics. He wrote the tunes mostly for television specials and all with Seuss’s clever wordplay and sing-song rhyme pattern. For instance, in TheCat in the Hat, a television short released in 1970, and based on his first children’s book, Geisel wrote several original songs including the bouncy, “The Moss Covered Three-Headed Family Gradunza”

There’s a gradunza-snitcher in the house. Things will never be the same without it. How dear to my heart was that beautiful gradunza. That my old feline father bequeathed to me. That old family gradunza, The old, three-handled family gradunza, The old, moss-covered, three-handled family gradunza. That hung on the family tree. I’ve been burgled–thwertled by a fish.The old, moss-covered, three-handled family gradunza

The catchy “Cat, Hat:”

Cat, hat, in French, chat, chapeau. In Spanish, el gato in a sombrero. He’s a cat in a hat, he’s a chat in a chapeau. He also is a gato in a sombrero. Ole, Ole, Ole, Ole-o.

And the playfully teasing, “Calculatus Eliminatus:”

When you mislaid a certain something, keep your cool and don’t get hot. Calculatus Eliminatus is the best friend that you’ve got. Calculatus Eliminatus always helps an awful lot. The way to find a missing something is to find out where it’s not.

One song in particular, “I’m a Punk,” introduced such ridiculously pleasing locutions as crontunculous, gropulous, poobler, and schnunk.

While everyone understands the meaning of punk, being a “schnunk” needed some explanation. But when the Cat sings, “nobody, likes me, not one tiny hunk,” everyone gets the idea.

Seuss’s writing style is often credited to a Life magazine article in 1956 that criticized children’s reading levels, specifically “primers” or textbooks with simplified words and phrases, like “Dick and Jane.” Geisel was asked to write a story using a vocabulary list of just over 200 words. He picked the first two words that rhymed, cat and hat, and went from there. It certainly wasn’t like any story in a textbook, that’s for sure, and critics praised “The Cat in the Hat” for its originality.

Several years later when Seuss wrote the lyrics for songs in his television specials, he seemed to relish the opportunity to ratchet up the silliness even more. Seuss’s words just seemed to work with music, oftentimes using traditional melodies, sometimes with an original score. The man credited with composing or arranging most of the music for Seuss is Dean Elliott, a Midwesterner from Wisconsin, who conducted orchestras for the Tom and Jerry shorts before hooking up with Seuss. Later he worked with Bugs Bunny creator Chuck Jones.

Seuss’s most popular song is one we hear every year around the holidays. In it, an unmissable deep voice groans about a Grinch who has a “heart full of unwashed socks” and a “soul full of gunk.”

Written in 1966 for the TV special “How the Grinch Stole Christmas,” Seuss enlisted a voice actor named Thurl Ravenscroft to sing the lead on the song even though Boris Karloff was the voice of the Grinch in the special.

Karloff reportedly could not sing and Ravenscroft was hired . But Ravencroft’s name was never listed among the credits and Karloff mistakenly got most of the acclaim. Seuss was reportedly furious and apologized for the oversight. Ravenscroft was also the voice of Kellogg’s Tony the Tiger (“They’re Great!”).

“You’re a Mean One, Mr. Grinch,” is an unconventional Christmastime staple. The song never mentions Christmas, but rather teases with crafty metaphors, comparisons and contradictions all designed to point out what an awful crank the Grinch – now a symbol of holiday grumpiness – can be.

You’re a mean one Mr. Grinch

You really are a heel.

You’re as cuddly as a cactus,

And as charming as an eel,

Mr. Grinch!

The song is instantly recognizable, charming and vintage Dr. Seuss. The songwriter.
